How do I develop a quality landing page?

Developing a quality landing page is critical to the success of your website. Google looks at various items to determine if your landing page will give visitors a great experience. The three main factors for a landing page are:

1. Original content (no duplicate) and Relevancy. Is your content informative, clear and useful?
2. Transparency. Can visitors easily find your products, services and contact information?
3. Ease of navigation. Is your site layout simple or do you have lots of links or information all over the page that makes it confusing for visitors?
